Solution Overview
Problem
Current surgical devices for treating cartilage are inefficient in excising large amounts of cartilage quickly, as they often require extensive time and may cause excessive heat damage to surrounding tissues.
Innovation Solution
An ultrasonic surgical system that heats cartilage to 120° C or higher within 2.2 seconds using an ultrasonic excision device, allowing for precise excision while minimizing heat insult to adjacent tissues by controlling temperature and vibration amplitude.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional surgical devices are used to excise cartilage, then the surgery time becomes long, but the productivity increases when using the new ultrasonic excision device
Solution Approach 1:
The patent employs ultrasonic vibration of the excision device at high frequency to rapidly excise cartilage. The mechanical vibration enables the excision unit to remove large amounts of cartilage in a short time, directly resolving the contradiction between excision speed and surgery time by transforming mechanical energy into efficient cutting action.
Solution Approach 2:
The patent controls the temperature parameter by limiting heating to 120°C or higher within 2.2 seconds, and adjusts the vibration amplitude parameter to optimize excision efficiency. By precisely controlling these parameters, the device achieves high productivity while preventing excessive heat damage, thus improving excision speed without sacrificing safety.
2Productivity
If higher temperature is applied to excise cartilage faster, then the productivity increases, but the heat insult to surrounding tissues worsens
Solution Approach 1:
The patent precisely controls the temperature parameter to be 120°C or higher but limits the heating duration to 2.2 seconds or less. This parameter control enables rapid cartilage excision while minimizing heat transfer to surrounding tissues, directly resolving the contradiction between excision efficiency and heat insult by optimizing the temperature-time relationship.
Solution Approach 2:
The patent applies high temperature briefly to rapidly excise cartilage then immediately stops heating. This rushing through the heating process allows the excision to complete before significant heat can diffuse to surrounding tissues, resolving the contradiction by completing the useful action quickly before the harmful effect can propagate.
3Productivity
If the excision device operates at high power to remove large amounts of cartilage, then the productivity increases, but the heat damage to surrounding tissues worsens
Solution Approach 1:
The patent employs periodic ultrasonic vibration with controlled duty cycle, activating the excision device in brief intervals. This periodic action allows high power delivery during vibration cycles for efficient cartilage removal, while off cycles allow heat dissipation, preventing heat accumulation and damage to surrounding tissues.
Solution Approach 2:
The patent maintains continuous ultrasonic vibration to continuously excise cartilage without interruption, maximizing productivity. Simultaneously, the continuous action is controlled within 2.2 seconds to prevent excessive heat buildup, resolving the contradiction by sustaining useful excision action while limiting total energy input to prevent harmful heat damage.
